WASHING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 732,105, dated June 30, 1903. Application liled June 23, 1902. Serial No. 112,894. (No model.)

T all whom, t may concern:

Be it known that LWILLIAM W. MUEPHEY,

ing-machines, and more particularly to that class thereof known as suction-machines, in which the water is forced alternately in opposite directions through the clothes, thus thoroughly cleansing them without the use of rubbers or pounders commonly employed to eiTect the same operation.

The invention consists in the novel features of construction and combination, all of which will befullydescribed hereinafter and pointed out in the claims.

In the drawings forming part of this specilication, Figure l is a perspective view illustrating a Washing-machine constructed in accordance with my invention and showing the practical application of the same. Fig. 2 is a longitudinal sectional view of the same. Fig. 3 is a sectional view of one of the cylinders. Fig. 4 is a transverse section on the line 4 4 of Fig. 3. Fig. 5 is adetail sectional view of one of the suction-heads.

In carrying out my invention I employ a base-board A,mounted upon a suitable central support A', the board projecting beyond the central support at each side, so that a tub B can be arranged beneath each projecting end of the base-board A. A cylinder C is arranged upon suitable brackets C, attached to the base-board adjacent to the opposite ends, and

pivoted centrally upon the base-board is a vibrating hand-lever D, slotted longitudinally, as shown at D', to receive a cross-pin E', carried by the piston-rod E, which works through the heads of the cylinder C, saidpiston-rod having a piston F at each end. Thus each cylinder is provided with a piston F, and each piston has openings F and flap-valves F2, which are adapted to close the said openings at certain times. A suction-pipe G is connected to the outer end of each cylinder C, and the check-valve H is arranged between the end of said pipe and the head of the cylinder for the purpose of checking the return of the Water sucked into the cylinder through the pipe G. Perforated suction-head I is arranged upon the end of each suction-pipe G, and these suction-heads I are adapted to rest upon the top of the clothes contained within the tubs B. A water-supply pipe K is connected to each cylinder at the end opposite the suction-pipe, and each supply-pipe K leads to the bottom of the oppositely-disposed tub, so that the Water sucked into the cylinder from one tub is discharged through the pipe K into the opposite tub. It is obvious from the arrangement of the flap-valves upon the piston and the check-valves at the ends of the suction-pipes that at each stroke of the piston water will be drawn up through the suction-pipe G into the cylinder C. At the same time the Water within the cylinder is forced out through the discharge-pipe K into the opposite tub, so that upon the return stroke of the piston the water from the opposite tub will be drawn up through the opposite suction-pipe, and these operations are continued until theclothes are thoroughly cleansed, a continuous circulation of the water through the clothes being obtained.

A check-valve L is arranged at the upper end of each supply-pipe K to prevent the water'being drawn back into the cylinder upon the return stroke of the piston.

It will thus be seen that I provide an exceedingly cheap, simple, and efficient construction of washing-machine which will thoroughly cleanse the clothes contained in two tubs'or receptacles and without the aid of pounders, rubbers, or agitators.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a' washing-machine, the combination with a suitable base, of cylinders mounted on opposite ends thereof, a piston working in each cylinder, a slotted lever pivoted between the cylinders, a piston-rod extending between the two pistons and passing through the slotted lever, pins on the piston-rod adapted to be engaged by the lever, and ileXible supply and discharge pipes connected to opposite ends of each cylinder.

2. In a Washing-machine, the combination IOO with a suitable frame, of tubs on either side each tub to the inner end of the cylinder discharging into the other tub.
